Airway management is a key skill in emergency and critical care settings, as maintaining a clear airway is essential for adequate oxygenation and ventilation.
Head Tilt-Chin Lift Technique
The head tilt-chin lift maneuver is an essential technique primarily used in patients without suspected cervical spine injuries. To perform this maneuver, one hand is placed on the patient’s forehead, and gentle pressure is applied backward to tilt the head. The fingertips of the other hand are positioned under the chin, lifting it upward. This action extends the neck, moving the tongue away from the back of the throat and reducing the risk of airway obstruction.
Jaw-Thrust Maneuver for Cervical Spine Precautions
In cases where a cervical spine injury is suspected, the jaw-thrust maneuver is preferred to avoid neck movement. The rescuer places their fingers behind the angles of the mandible and applies upward and forward pressure to move the jaw forward. This technique effectively opens the airway while minimizing cervical spine movement, making it ideal for patients with possible spinal injuries. However, it may not be as effective as the head tilt-chin lift for clearing the airway if there is significant soft tissue obstruction.
Oropharyngeal Airway (OPA) Insertion
For unconscious patients without a gag reflex, an oropharyngeal airway (OPA) can help keep the airway open. The OPA prevents the tongue from blocking the airway, ensuring a clear path for airflow. Selecting the correct OPA size is crucial; the appropriate size is measured from the corner of the patient’s mouth to the angle of the jaw. Insertion begins with the tip of the OPA facing the roof of the mouth. As it advances, the OPA is rotated 180 degrees, allowing it to rest over the tongue, reducing the risk of trauma to the oral mucosa and ensuring proper placement.
Bag-Valve-Mask (BVM) Ventilation
For patients experiencing apnea or inadequate breathing, a bag-valve-mask (BVM) device is used to provide manual ventilation. Place a well-fitting mask over the patient’s nose and mouth, creating a tight seal using the “E-C” clamp technique: the thumb and index finger form a “C” shape around the mask, while the remaining fingers form an “E” along the mandible to stabilize the mask and reduce air leaks. The rescuer then squeezes the bag every 5–6 seconds, observing visible chest rise as a sign of adequate ventilation. BVM ventilation can be performed with or without supplemental oxygen; using oxygen increases the amount delivered. It can also be combined with adjuncts like OPAs or nasopharyngeal airways (NPAs) to improve ventilation in unconscious patients.
Essential airway management includes several key techniques
The head tilt-chin lift technique involves placing one hand on the forehead while using the other hand’s fingers to lift the chin. This helps clear the airway by moving the tongue away from the throat.
When a cervical spine injury is suspected, the jaw-thrust maneuver should be used instead. This maneuver opens the airway without neck movement by placing fingers behind the jaw angles to move the mandible forward.
For unconscious patients without a gag reflex, an oropharyngeal airway, or OPA can be inserted to prevent tongue obstruction.
The OPA is selected by measuring from the corner of the mouth to the earlobe. It is initially inserted with the tip facing the roof of the mouth and then rotated 180 degrees to align with the tongue.
For apneic patients, a bag-valve mask, or BVM, is used by placing the mask over the nose and mouth, creating a seal with the thumb and index finger in the "C" shape around the mask while the remaining fingers form an "E" on the mandible; the bag is squeezed every 5–6 seconds to ensure visible chest rise.
